Maybe this is a good time for you to expand on this subject and suggest some suitable instruments for measuring the electrostatic charges / ion winds and how they contribute to power output.

Here is akula's approach:
The instruments based on https://en.wikipedia.org/wiki/Electrometer are good start for finding Tesla coil frequency timings and relation between how much of charges are being attracted into grenade. For a start akula suggested to place small foil near the top of Tesla coil. Then connect foil to the few picofarads capacitor then to the ground for substitute of grenade. Then start looking on the scope for BEMF like kicks on the capacitor and maximising them right after Tesla is getting switched off is the crucial for finding what voltage and frequency is required for the Tesla coil. Only after finding frequency of the kicks and creating their resonant condition for the constant current flow the grenade coil is made as receiver for this exact condition.
This is what still waiting to be tested when I will get time in the lab.

Cheers!

Thanks for that T1000. An opportunity here to progress!

apecore,

Thanks for conducting the tests. This is where I got to with my setup and the results you show are much the same as mine. You will see from the scope waveforms that the HV is playing havoc with gate signals and that better / more stable performance can be had using a single mosfet yoke driver. Connecting the inductor only appears to increase the interference.

With a single mosfet driver, I was able to completely extinguish my bulb with hand capacitance. I have reached no conclusion about whether the HV interference to the push-pull and lighting effects we see, or a single mosfet driver are necessarily important steps to the final solution. However, I am fairly sure that the increased bulb brightness when the Kacher is switched-on is due to interference on the mosfet gate, resulting in a more powerful output drive to the yoke and therefore increased induction into the 28-wire and 3-wire secondary yoke windings. I suspect that the HV interference to one of the mosfets is badly switching, causing a grounding-out of the supply line, thus increasing current draw.

Hi Hoppy,
Thanks for the explanation...it is a plausible conclusion.
With that in mind there is such as a linearity in power in/power out.
As i see there is already some discussion going on about measurements.
I d like to introduce the term " critical parameter"...and hope we could define them....and if we will be able to measure them with certain accuracy we will also be able to manage improvements in a controlled manner.
The next parameters are valid to be labelled as critical;
1- power in kacher (Volts&Amps)
2- power in push_pull (Volts&Amps)
3- power out (Volts&Amps)
4- electrostatic charges (emitting&absorbing)
5-and maybe some more...

Next step is to find a reliable measuring method
If that is achieved unindipendent setups will give a efficiency rate wich will point out wich setup variant is most valid.

Without starting measuring at these parameters this whole process wil stuck and only the "lucky" ones will achieve results.
But considering the complexity is the change for luck also same as winning the jackpot.

So i am glad Hoppy opened the discussion according measurements and that T1000 is taking some action in ion winds.
I will and if you all agree will take the action to make an overvieuw of the criticals..... as mentioned.
Of course with help of you all.

Thanks and greetings

I'm working for coils now. I found the point of resonance for grenade coil at 600 Khz and coil Caher the same resonance, 600Khz.
I do not know if it is ok but the amplitude is huge for both coils at around 600 Khz.

   Hoppy:
   Sorry, but I'm not interested in what YOU want from me.  While you are provide NOTHING at all.
Britts have a conception of what is called a "fair exchange". Where is your part?
   Do your own work and tests, instead.  Or just keep sitting on your hands, like you've been doing.
   Talk is cheap.
   
   As you feel that what I've provided up to now is of no use,  I won't waste more time trying to discuss my results, with you.
   There are others that may appreciate what I'm doing. I'll continue in PM, with them, if they are interested. 
   I don't want to hear any more about this. Do your own work, and tests, then show us all how well your measurements work out.
   I do what I want, when I want, and in my own way. Period.
   Neither Akula nor Ruslan have ever shown any input to output readings, nor needed to. 
You must think they are a lost cause as well?  Well, I don't agree.

   Once apecore shows that the input from his non self runner will always be less than the output, you will be satisfied?  I doubt it.
Will this proof anything?  Yes, that we are wasting time measuring what is obvious.
